Isolation of lytic phages of E. amylovora.
Of the Erwinia spp. and strs tested with 10 lytic phages, 1 str. each of E. rhapontici and E. stewartii and 8 of E. herbicola were sensitive to at least 1 phage but none of these was sensitive to all the phages. In contrast, 165 of 175 strs of E. amylovora were sensitive to all the phages and the other 10 to at least 1 phage each. This paper was presented at the Fifth International Workshop on Fireblight, held in Diepenbeek, Belgium on 19-22 Jun., 1989.
